Trestman developing playbook

Much like Halas Hall, the Bears’ offense remains under construction.

Bears coach Marc Trestman said Thursday that he and his assistant coaches continued to work on creating a new playbook for the offense. Once that happened, Trestman said, Jay Cutler and his teammates could start studying the plays.

Trestman said he had spoken with about two-thirds of the players on the Bears’ roster in preparation for next season. Trestman said he spoke on the phone for with Brian Urlacher for more than 30 minutes about the franchise and about football in general, but he was noncommittal when it came to Urlacher’s future with the team.

As construction crews worked outside to expand Halas Hall, the Bears introduced each of their new assistant coaches, including offensive coordinator Aaron Kromer and defensive coordinator Mel Tucker. The only vacancy that remains on Trestman’s staff is for a wide receivers coach.

Although the offense will be renovated, the defense likely will not be overhauled. Tucker said he planned to maintain a 4-3 defensive scheme similar to what was in place during Lovie Smith and Rod Marinelli’s tenure with the team.
